本书总结了使用Python进行计算工程和科学计算的一些核心思想。重点是介绍一些与数值算法相关的基本Python(编程)概念。后面的几章涉及数字库,如numpy和scipy,它们比这里提供的空间要大得多。我们的目标是让读者能够独立学习如何使用可用的文档(在线和通过包本身)使用这些库的其他功能。

目录内容: Chapter 1 Introduction Chapter 2 A powerful calculator Chapter 3 Data Types and Data Structures Chapter 4 Introspection Chapter 5 Input and Output Chapter 6 Control Flow Chapter 7 Functions and modules Chapter 8 Functional tools Chapter 9 Common tasks Chapter 10 From Matlab to Python Chapter 11 Python shells Chapter 12 Symbolic computation Chapter 13 Numerical Computation Chapter 14 Numerical Python (numpy): arrays Chapter 15 Visualising Data Chapter 16 Numerical Methods using Python (scipy) Chapter 17 Where to go from here?

TVTropes is a wiki that describes tropes and which ones are used in which artistic work. We are mostly interested in films, so after releasing the TropeScraper Python module that extracts data from this site, in this report we use scraped information to describe statistically how tropes and films are related to each other and how these relations evolve in time. In order to do so, we generated a dataset through the tool TropeScraper in April 2020. We have compared it to the latest snapshot of DB Tropes, a dataset covering the same site and published in July 2016, providing descriptive analysis, studying the fundamental differences and addressing the evolution of the wiki in terms of the number of tropes, the number of films and connections. The results show that the number of tropes and films doubled their value and quadrupled their relations, and films are, at large, better described in terms of tropes. However, while the types of films with the most tropes has not changed significantly in years, the list of most popular tropes has. This outcome can help on shedding some light on how popular tropes evolve, which ones become more popular or fade away, and in general how a set of tropes represents a film and might be a key to its success. The dataset generated, the information extracted, and the summaries provided are useful resources for any research involving films and tropes. They can provide proper context and explanations about the behaviour of models built on top of the dataset, including the generation of new content or its use in machine learning.
